As a kid I was hooked on Pokemon, Digimon and Yu-Gi-Oh. After a anime-free gap of a few years my friend lent me the first series of Bleach and soon after I picked up the second, from their I was hooked again and began searching for more anime to watch.

Found vocaloid through a PewDiePie video back in 2013, got hooked on vocaloid, then a friend recommended Death Note, after having a huge geek freakout when he fould out I was getting an interest in anime (the school I went to, it was pretty hard to find anyone else solidly into geek stuff) and been into it ever since.
(he also recommended high school of the dead and High School DxD, both are SUUUUPER overloaded with fan service, still good though ).
